28  The heart of the righteous ^yponders how to answer,

but ^zthe mouth of the wicked pours out evil things.

23  ^kA prudent man conceals knowledge,

^kbut the heart of fools proclaims folly.

16  ^qEvery prudent man acts with knowledge,

^rbut a fool flaunts his folly.

2  A fool takes no pleasure in understanding,

but only ^zin expressing his opinion.
